We'll Sing Again

So, do you remember when The Colbert Report went off the air and had that spectacular finale with piles of public figures pouring out on stage and across the world and into outerspace -- and you could identify some of them, but not all?

I had a hankering to watch it again (and use the word "hankering") -- but also found a version that had pretty much everyone (except the massive final group on stage) identified.

Sing along with Stephen...
